Science is a strange and mysterious subject. Past the boring teachers and stupid ten year series, Science holds much mysteries which stimulate the mind and open up the imagination.
For example, why do all physics teachers have such lousy english? I've yet to see a physics teacher who comes up with perfect grammer in his slides and test papers. It is also the strangest branch of science to be bad in english in. After all, physics is supposed to explain the world's greatest mysteries to the people. Perhaps the world is not so mysterious after all. Perhaps all the strange questions and chaos theories are due to miscommunications between scientists.
Another think about science. Sometimes they tend to contradict other subjects. For example, in geography, we would learn that euthrophication is due to nutrients in the water causing surface plants to reproduce rapidly resulting in the cutting off of sunlight. This causes the bottom dwelling plants to die and when decomposers act on them, oxygen is removed resulting in the death of other aquatic organisms.
In chemistry, we learn nothing of surface plants but merely that algae will grow and when they die, the resulting decay will kill the animals. It is pretty much the same in biology. Which theory then, should we subscribe to? Or do we have a seperate answer for each question? No one knows...
Finally, there are the stange places that science will lead you. Apparrantly, according to the law on conservation of energy, energy cannot be created or destroyed, but can only be transformed from one form to another. This means that once energy is here, its here to stay. Fine, I can accept that. Now to biology, which says that energy flows from the sun in a non cyclic manner, meaning that energy is constantly supplied by the sun. Now non cyclic means that energy is lost. If both facts are to hold, this will mean that there is an accumilation of energy on earth. So where exactly does this energy go? According to the first law, it cannot simply disappear, and according the biology, it has to be constantly coming in. this will lead you to mean that the earth itself is gaining energy every second. By gaining, energy, according to the kinetic particle theory, the atoms that make up earth, as well as the layer of air around it, will be gaining energy every second. Using the particle theory again, this will mean that earth is getting hotter and hotter every second. Does this mean that earth will one day suddenly explode? Now earth has had several billion years worth of sunshine. No prises for guessing how much energy that amounts to.
Now, if you use einstein's theory that e=mc^2.
m=e/c^2
so my the amount of energy we have received, it will be my conclusion that if the energy does not go anywhere else, it will be converted to matter. This will mean that the earth is gaining in mass every day. Is this the true for reason for the earth's expanson as opposed to conventional theory that the expansion is simply due to earth getting older and gravity getting weaker?
If so, it might even mean that every thing on earth is expanding, and expanding in proportion such that til all seems normal to earth. Perhaps it is this, with the effect of inertia that causes gravity. so the pulling force we experience is not due to attraction between matter, but simply the pushing of the earth as it expands hence creating a force against us and as newton's third law of motion states , that any force has an equal and opposite force, the 'gravity' we feel is simply the opposite force we exert upon the earth.
Now for my final theory. Global warming apparantly causes a rise in sea levels. Bullshit.
As water cools down, it contracts. However, at 4deg C it starts to expand again. This explains why ice floats on water instead of sinking down, because its volume has increased while its mass remained constant, its density is thus decreased. The thing here is that the volume of ice below the surface(about 2/3), is acutally the original volume of the whole block of ice when it was liquid. This will mean that even if the icebergs melt, the sealevel will remain constant. So wheres the worry about rising sea levels?
Furthermore, with an increase in global temperature, the capacity of air to hold water vapour increases. This will mean that more water gets evaporated into the atmosphere. With more watervapour in the atmosphere, more clouds will form. More clouds means that less sunlight will penetrate the earth, and it will rain more often. Does that sound like the earth will be getting hotter? I should think not...
